One-object-one-code-based user consumption behavior automatic clustering method and application system

The invention discloses a one-object-one-code-based user consumption behavior automatic clustering method and an application system, and relates to the field of data mining, and the method comprises the following steps: obtaining user code scanning data, and carrying out the preprocessing of the data, and generating first data; labeling the first data by using a labeling algorithm, performing automatic group division by using a clustering algorithm in combination with consumer historical data, and summarizing other behavior records of the user to generate second data; storing the second data, and portraying the user according to the second data; and according to the user portrait, actively touching the user and/or passively touching the user, and determining a marketing scheme when the user scans the code next time. The system further comprises a data acquisition module, a data processing module, a label and clustering module, a data storage module, a user portrait display module and a precision marketing mod
